Thousands of years ago, Confucius introduced the concept of jen. According to him, a person of jen “brings the good things of others to completion and does not bring the bad things of others to completion.” In other words, jen represents our ability to make the world a better place…but also a worse one.

In this lesson students explore the concept of the jen ratio — the ratio of positive to negative observations in our daily lives — and use it to discuss how the what we see influences the way we experience the world.

Students will

  • Use ratio language to describe the relationship between two quantities.
  • Compare ratios.
  • Find equivalent ratios.
  • Identify ways to improve the jen ratio of oneself and others.

Before you begin

No prior knowledge of ratios needed.
